Serum or plasma substance concentration (qualitative) for albumin

What Albumin Tests Measure

Albumin is a protein produced by your liver that plays a critical role in keeping fluids within your blood vessels. Low albumin levels may indicate conditions like kidney disease, liver problems, or severe infections, while very low levels could suggest malnutrition or protein loss from the body. This test does not provide a specific numeric value but helps determine if further investigation is needed.

Why It’s Done

Your healthcare provider may order this test to monitor conditions affecting protein levels, such as chronic kidney disease, liver disease, or severe infections. It can also be part of routine blood work to assess overall health or nutritional status.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is processed to separate serum or plasma, which is then tested for albumin presence. Results are qualitative, meaning they indicate whether albumin is present in expected or unexpected amounts.

What to Expect Before the Test

No special preparation is needed, but you may want to avoid eating or drinking for a short time before the blood draw if instructed by your provider. Wear comfortable clothing with an easy arm hole for the test.
